Curious as to what the members of the OT think...
Legally the pedestrian was wrong but both of you could have done better here. Right of way doesn't keep you out of the hospital.
A buddy of mine was in a similar situation to yours in Arlington (Virginia, not Texas) and ran over a pedestrian who stepped in front like that.
He was very fortunate that a cop happened to be right behind him watching the whole thing. Not only did the pedestrian spend time in the hospital, but also got the ticket. True story.
The ped should have made sure you saw him before stepping into the street, no matter what the sign showed. If you are about to cross a street (on foot, on a bike, whatever) always make sure drivers see you, especially when you are doing so in front of a car driven by someone looking in the other direction.
Similarly, if you are that driver look to the right before you make that turn instead of after you start moving. If you are not fully aware of your surroundings you are dangerous to others (and potentially yourself) no matter who has the right of way. Sure, you have to check to the left to make sure it's clear - but check to the right also next time.
